- mime.- am n, sci-1m. aun Io. 4 am. Todlwbomttmyoonwm ary over and under chutes 8 and 9 the Be it: known that I, Cnaauas S. Faaaaa, a citizen of the United States, residing at Dunmore, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Slate- Pickers, of which the iollowing is a specification, reference being bad to the accoming drawings. is invention relates to im rovements in machines for se arating slate fiom coal and more particular y those of the type set iorth in-my Patent Number 920,939, grantedMay 11 1909.

I 16 The object of the present invention to "improve and sim lify the construction and o ration of mac tines of this character and thfreb render them more etiicient.

Wi l the above and other objects in view,

I gotta: invention consists of the novel mmtruetions bein tion, combination and arrangement of mrts, h'etieinafter fully described and claimed. and illustrated in the accompanying drawings in which Figure 1 is a vertical longitudinal section 'throu h a portion of a slate picking machine embodying m improvements; Fig. 2 is a we parts shown in Fig. l, porplan view of t brokcnaway and Ill section;

Figs. Ban 4 are detail sectional views taken 'respectively on the planes indicated by the 'lines 84-34 and 85-35 in Fig. l; and Fig. .5 is a detail sectional view through a portion of a slate picker showing an im roved formof oscillatory feed member am a coactmg reci'prmratory separating member;

, tum;

, Fig. 6 is a plan view of parts shown in Fig. :5, portions being broken away and in sec- Fig. 7 is a detail edge view of the uscillatory feed member showing the cam thereon; and Figs. 8 and 9 are vertical sec- ",tional views through two general forms of j flllte pickers in which my improvements ferring more particularly to Fig. l of ,t e drawing, 1 denotes the side plates or fitiyebe employed.

alls of a substantially rectangular frame of an upper receiving chute 2,

isposed in an inclined position and within which may be arranged one or more groups of separating mechanisms, each consisting a discharge "chute 8, an oscillatory feed member 4' bei dischar g;e chute, an udjustably mounted twcen said chutes, an ndjustably mounted retarding surface 5 at, the lower edge of the arating or dividing member 7" and stationchute 9' forming the upper portion oi the receiving chute of the next lower group of se nirating mechanisms.

h'e retarding surface of member 5 is here shown as in the form of a block of stone or other suitable material arran d in a slidahle support or car 6' provide( with grooved supporting wheels to travel on stationary track bars 71 secured to the in ner faces ofthe side plates 1'. The car or carriage 6' has a body portion or frame forming a pocket to,recei\'e the block 5". and at its u ipcr edge is a plate which slides beneath t ie chute 3" w en the car is -ad'usted, as will be underst .tln reference to ig. 1. The car ti is adjusted b' providing two chains or flexible elements i2 and anchoring their upper ends at 73 to the side plates 1'- and attaching their lower ends to a transverse winding shaft 74 rotatable on hearing brackets 75 projecting from the ear or carriage ti. One end of the shaft 74 projects through an opening it? in the adjacent plate 1 and has fixed to it a hand wheel 77. Also fixed on said end of the shaft within the frame. is a ratchet wheel 78 with which (-0- acts :I pawl 79 pivoted on the car as shown.

.-\s above stated, the car or carriage ti may be of any form and construction, but it is preferably const rncted of angle metal bars as indicated, and inorder to dispose the upper surface of the block 5 at. a slightan It: or inclination when neceasarv or desirab e, set screws 80 may be prorh ed in the lowermost angle bars to im nogc against the bottom of the block 5. 'l iis block may be. carborundum, emery, stone or other material which will tend to retard the downward movement of the slate.

The separating or dividing member 7' is here shownas mounted for vertical sliding movement and in the form of an angle metal bar disposed ud'acent the u iper edge of the chute 8'. Suit member 0 bar 7 has the ends of its vertical flange slidabl arranged between spaced anglemetal guioe strips 81 secured on the inner opposing faces of the side plates 1. Said member or bar 7' is adj ustcd by providing on a transverse, shaft 82 eccentrics 88 which have strapjrms 84 pivotally connected by means of brackets 85 to the member or bar 7. The shaft 82 is mounted in suitable bearin ed of the side plates 1 an has on one end a mil wheel'86 by means of which itima'y be rotated to cause the eccentrics to raise or lower said member or bar 7. To retain the latter in adjusted position a ratchet wheel 87 is fixed to the shaft 82 and en ged by a pawl 88 pivoted on the adjacent si i e plate 1'. The oscillatoig feed member 4' may be constructed as iown in Fi 1 and awe pockets on one side onl of i s pivot, but I preferably make it don lo as shown at 4' in i 6 and 7 and employed in connection wit 1 it are laterally reciprocating slate defleeting members 62. One or more of the members 62 may be provided in advance of each of the feed members 4' and they are mounted for lateral reciprocato movement so that they resemble shuttles. ach of the members or plates 62 is comparatively thick so that it projects a siitlicient distance above the plane of the upper surface of the chute 2 or 9, to stop he pieces of slate which are usually flat, but not sufliciently large to stop pieces of coal, the latter being of polvgonal shape and hence bound over the plate or )latcs 62. These plates 62 are also preferably of triangular aha and are arranged with their apcxes turn upwardly and the inclined portions of their front, or upper edges are preferably notched as shown at 68, so that as they reciprocate they will stop the pieces of slate and push them laterally into the kets formed in the feed member 4'. Sai shuttle plates or members 62 are secured b rivets 64 or the like to plates 65 arran for sliding movement on the top of the chute 2*. (iuide pins 66 in the form of bolts, project from the lutcs 62, 65, through guide slots 67 forinet in the chute or other support, whereby said plates 62 will be guided in their reeipi'ocatorv movement transversely of the device. The shuttle plates 6;. are preferably ieeiprmated by anguarly arran ed cams 68 provided on the upper edge 0 the oscillatory feed member 4' and adapted to work in recesses 69 formed in the rear or lower edges of said plates 62,65. It will be seen that as such member 4' oscillates vertically, the cams 68 will reciprocate the shuttle plates 62 laterally. The oscillatory na-iiiber 4" has its pivots l5 arranged lllttt'lllt'tllttit! its front and rear edges, and along its front edge in its top are formed pockets II" which are sepai'alml bv ribs or )artitions 11" from similar pockets 11' ormed in the upper surface of said member ad'acent its lower or rear edge. 1y improvements above described may be embodied iii'various kinda of separating machines but they are particularly adapted for use in machines auci prior patent above mentioned, and in the well known types of slate picking machinery shown in Figs. 8 and 9 of the drawin In Fig. 8, 1 denotes the side plates of t e frame, 2 the receiving chutes, 8 the dischar chutes, 4 the oscillatory feed members, 5 t

as set forth in my retarding surfaces, 7 the separating or dividing members and 8 and 9 the over and under chutes. The machine shown in Fi 8 is a three drop slate picker, and theose I atory feed members 4 of the two uppermost gioups of separatin mechanisms are connected to eccentric raps 19 operated from a main drive shaft 17 which may contain a belt wheel 25; and the member 4 of the lowermost group of separatin mechanisms is connected b a link 21 to t 0 member 4 of the interm iate u In Fig. 9 the s ate picking machine is of the zigzag t pe, each group of separating mechanisms in disposed above the next lower grou and inclined in an opposite direction, an the oscillatory feed members of the several groups being connected by links and dfrifen from a mafin tll'lvfllflhtift at the top 0 t ie supporting rame. n i 9, 2" denotes the receiving-(mates, t3 the discharge chutes 4" the oscillating feed members. and 5" the retarding surfaces. The several feed members 4" are connected to each other by links 19" and the uppermost member 4 is connected toan arm 19' extending from an eccentric on the main drive shaft 17''. It is thought. that the applicacation of my improvements to this machine, and also to the one shown in Fig. 8 will be ieadily understood without furtherexplanation.
